DUST-SEPARATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 314,498, dated March 24, 1885.

Application filed December 9, 1884. (No model.) Patented in England February 28, 1883, No. 1,053; in France August 28, 1583, No.157,277; in Belgium August 29, 1883, No. 62,443, and in Italy September 3, 1483, No. 15,841.

To LZZ whom, it 77mg/ concern.-

Be it known that I, PIETER VAN GELDER, of Sowerby Bridge, in the county of York, in the Kingdom of England, have invented certain new and useful Improvements in Dust Separating Machines, (for which I have received Letters Patent in England dated February 28, 1883, No. 1,083; in France dated August 28, 1883, No. 157,277; in Belgium dated io August 29, 1883, No. 62,443, and in Italy dated September 3, 1883, and numbered. 15,841,) ot' which the following is a specification.

My invention relates to an improved apparatus for separating dust from the air in iiour- I5 mills; and it consists in a novel construction of the same, as hereinafter fully set forth and claimed. lt is well illustrated by aid of the accompanying drawings, in which- Figure 1 is a sectional elevation, and Fig. 2

2O a plan View, of the apparatus. I

In these, A is a tank to hold the water, with preferably a constant stream of water running through, which overflows through the pipe B.

C is a pipe or conduit which conveys the 2 5 dust-laden air from the source where it is charged to the tank. The end of this pipe appreaches within a short distance of the surface ofthe water in the tank.

D is abox or casing into which the end of 3o the pipe C projects. In the top d of this casing is cut a hole corresponding in contour with the cross-section of the pipe C, and which, though free to move up and down on the pipe, iits it practically air-tight, so as to prevent escape of any of the air or dust.

c is an india-rubber or leather washer attached to d `for the purpose.

E is a broad flange secured to the bottom of the casing D. The iiange E may be made of 4o wood or other light material, so as to iioat on the surface of the water. The under surface of the flange E is furnished with a series of pins, e, which prevent the air forming bubbles with the water, and thus carrying through with it the dry dust. These pins are prefer ably arranged as shown, being made of greater length toward the outside than nearer the center. The casing D is suspended from above by two rods, F, which are pivoted to 5o the counterweighted levers G, carried in bearings H, mounted in any suitable position above or in connection with the pipe C. The lower ends ofthe rods F are connected to the casing D by means of a frame-work, I, the casing being pivoted thereto, the whole forin 55 ing a univeisaljoint, allowing the casing D to freely swing, as if on gimbals., as the air passes through it and escapes under the iiaiige E. The forni of the pipe C in cross-section is immaterial, as it may be cylindrical, as in Fig. l., or rectangular, asin Fig. 2, and it is likewise apparent that theshape or contiguration of the box D and iioat E may be varied as desired.

Vhat I claim isw 6- 1. rFhe herein-described dustcol.lector, coniprising tube C, box or casing D, carrying iioat E, and tank A, filled with water or other liquid, as and for the purpose set forth.

2. In combination with tank A, containing water or other liquid, a discharge-pipe for dusty air extending nearly to the surface of the liquid, and a casing encircling the lower end ofthe pipe and resting upon the liquid, as and for the purpose set forth.

3. In combination with a tank containing water or` other liquid, a dischargepipe for dusty air extending nearly to the surface of the liquid, and a casing encircling the lower end of the pipe and provided with a fioat, substantially as shown and described.

4. In combination with a tank containing water or other liquid, a discharge-pipe for dusty air extending` nearly to the surface of the liquid, a casing encircling the lower end of' the pipe, and a iioat attached to the casing and provided with pins or teeth, as and for the purpose described.

In combination with a tank containing Water or other liquid, a discharge-pipe for dusty air extending nearly to the surface of the liquid, a casing encircling the lower end of the pipe, and a float attached to the casing and provided with teeth or pins increasing in length toward the periphery of the float, as shown and described.

6. In combination with a tank containing Water or other liquid, a stationary discharge pipe for dusty air extending nearly to the surl face of the liquid, a counterweighted casing roo encircling the lower end of the pipe and provided With a float.

7. In combination with a tank containing Water 0r other liquid, dustyaindiseharge pipe In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
